In succession to these files , I found that better scopings could be
made by not having background halide light onto the subject scope, so
addition of files are noted;
Formerly;http://groups.yahoo.com/group/teslafy/files/ATC/Dsc00309.jpg
described as;
Solid State 20 khz NST; scoping across 20.5 mh coil with bulb in
series; 10us/div; 50 volts/div
can be better shown by not having background halide light on
scope;and then turning up intensity of beam to reveal background
vibrations, this is then classified as;
Reduced Lighting background and increased beam intensity; Solid State
20 khz NST; scoping across 20.5 mh coil with bulb in series;
10us/div; 50 volts/div http://groups.yahoo.com/group/teslafy/files/ATC/Dsc00310.jpg
Notice how the background oscillations become noticed now with this
better scope technique. Normally the beam intensity must be turned
down because the shining of the halide had made that necessary. I
have worked a long time to make better scope photos, and this will be
the standard for the future. I now understand that the background
halide light is redundant for scope photos,but necessary for meter
photos: and it is better using the Sony camera to use the dark
background method for scopings. The Sony camera program called P
suite does a good job in making things noticable in its program of
adding lighting or subtracting lighting after the photo is made. This
was formerly a great problem in showing meter indications with the
former camera. The old camera was a piece of sheisse. Now better
scopings can be made in the future, knowing that a dark background is
better.

Notice the effect of very unusual triggered scopings on turning the
sweep rate up next to 5 us/div with triggered sweep; which is
necessary to gain coherent information on all these sweepings. The
uncohered signals sweep across the time frame faster than human
recognition can recognize, so these are all triggered scopings.

series; 5us/div; 50 volts/div : Dark Backgroundhttp://groups.yahoo.com/group/teslafy/files/ATC/Dsc00311.jpg
Now the inherent separation of polarities in these signals becomes
more apparent.
Next we can go up one more sweep rate to 2us/div.

See how the 90 degree vibrations have been accentuated by turning up
the sweep rate! They are there in the first place, but not noticable
so much at the lower sweep rates: but by turning up the sweep rate
and also using the technique of making the proper lighting with the
good camera, those things are better brought out!
